Firefox supportforum

Hello,

My Firefox routinely shuts down while I'm using my 2018 Macbook Pro, and the problem began when I updated my IOS to Big Sur This is a systemic problem with non-native apps ever since installing Big Sur. Apple won't address the problem unless I confirm that my non-native apps are compatible with Big Sur. Can you please confirm the most updated version of the Firefox Browser is compatible with Apple's Big Sur IOS? Can you also let me know if other users have experienced problems and if there is any fix?

latest version 88.0b6 still gives "can't load xpcom" message why is this still happening after 3 years of the problem in the history of upgrades. Don't tell me to check profile as I can't even start FF. I have done all the deletions as instructed by various experts but still get the message "can't load xpcom". Samuel Santos said download "83" to see if that fixes it I don't know if it did cause I then got "CAN'T FIND ENTRY POINT"

Firefox 87.0 (64-bit) on Ubuntu 20.10 is currently unusable as it won't open anything.

• Firefox opens with no page loaded.
• Clicking the single "getting started" bookmark does nothing.
• Entering a search term in the address bar and pressing 'enter' changes the url in the address bar but nothing is loaded and the page remains blank. There is no indication that anything is loading.
• Entering a url, such as "www.youtube.com", and pressing "enter" does nothing. There is no indication that anything is loading.
• Opening the menu by clicking on the burger icon, then on "preferences" does nothing except make the menu disappear (same with most of the options in the menu).

In the browser console I see some errors and no request info (see screenshot).

I've tried `sudo apt purge firefox` then installing again, which didn't help. The problem started with ubuntu 20.04 (I only updated to 20.10 to see if it might resolve this problem).

I've tried the "refresh firefox" option, starting in safe mode, and clearing the startup cache, which didn't help.

Any suggestions would be much appreciated.

I mistakenly deleted my firefox browser, I am running Mac OS 10.7.5 with a SSD on a Mac Pro desktop. I have been unable to download a new firefox browser because of the OS and hardware limitations. I sorely miss firefox. Is there any way to get an older version of firefox which will run on my computer? adnicastri@aol.com

After having installed the latest Firefox update Firefox starts but it does not react to any link inserted for display.

If have tried all three help solutions provided but it does not react, also a new installation changed nothing

The error message is: Starter process deactivated after error.

Could someone please help to make run it again

P.S. It was not possible to get the Troubleshooting information as I could not write this request on Firefox but had to use another browser

Hello all, after reinstallation my Firefox 88.0.1 on Windows 10 64 Bit does not go online. I can't open the settings. Other browsers like Opera and Edge are ok on the computer. Does anybody have any hints ? Many thanks, Volker

Over the last couple of days we are seeing instances of Firefox just disappearing from Windows 10 and just today from a Windows 7 pc. When I say disappears, the desktop shortcut becomes dead, click on it and a prompt to search for firefox.exe comes up. Checking Add / Remove programs shows Firefox to be installed. Checking C:\Program Files\Mozilla Firefox reveals empty folders with the exception of a couple of text files. Trying to reinstall the Firefox app, we are prompted with a message that Firefox.exe can't be found, and there is a button to browse for it. The only solution we have found for this is to copy the C:\Program Files\Mozilla Firefox folder from a working pc, and we just received a call from a user we did this for telling us that it is gone again. Any ideas?

Thanks.....

We have checked for viruses.

hello since update of newtest version of firefox 89.0 (64-Bit) the browser is freeze and i receive message "do you will wait or close the browser". When i press wait so the windows is reload and ask if i will do wait or close firefox. I have only possibility to close firefox. The problem is all time. When i have chance i can use firefox 2-3 hours without problems. Many time i open Firefox after 5 minutes its freeze.

Whats happen? before i have do make update not problems....

My System: Ubuntu 18.04.5 LTS with 89.0 (64-Bit) Firefox.

When i updated i lost all my bookmarks but my issue is that randomly firefox will just stop responding? when i open a new tab it wont load so i close the window and try to reopen it but an error message pops up saying im trying to open an older version and it forces me to 'make new profile' then it opens an older version and prompts me to update even though i already had, so i update and then i have to sign in to everything again. and this has happened multiple times so i started making bookmarks of all the tabs i had open so i dont lose them and them save them as backups, but i cant restore the back ups

I need to reload Firefox from a disk image after every reboot on my mac. This doesn't take much time but its an exercise after every boot up...Need to run the image, punch in credentials and then wait for the sync-up to see all the browsing history and bookmarks...Is there a fix to resolve this challenge?

I HAVE COMPLAINED BEFORE ABOUT THIS- \bing-ebay-google-wikipedia-amazon - CONSTANTLY -- DOWNLOADING ONTO MY FIREFOX - AND I DID REMOVE ANY THING CLOSE TO bing-ebay-google-wikipedia-amazon- I NOTICE SEVERAL PEOPLE ARE COMPLAINING ABOUT THIS PROBLEM- SO REMOVE THAT CRAP ADS OR I'LL FILE A FORMAL COMPLAINT- I WILL MAKE SURE THAT PEOPLE SEARCH THEIR FIRE FOX. THANK GOD FOE UNINSTALL TOOLS THAT CAN TRACK AND FIND YOUR SECRET AD ONS- NO ONE SHOULD HAVE TO SEARCH OR WORRY ABOUT FIREFOX PUTTING JUNK ON THEIR BROWSER- YOUR STATEMENT OF TRUST STATES THAT FIREFOX WILL NOT AD JUNK OR UNWANTED ADS.

I just recently updated my Macbook Air to Big Sur and downloaded Firefox to use as my default browser. Installation went smoothly and I am able to use the program as intended. When I click on an external link, an window pops up and tells I do not have permission to open the app and to contact my computer or network administrator for support.

I am not computer savvy when it comes to programming and would love any help anyone has to offer.

Most appreciative.

I am testing FF91esr for deployment later this year. Having a lot of grief with it.

For context; On most of our PCs the profile folder is NOT in the %APPDATA% folder. It lives on a different drive, typically drive F:\

This allows us a lot of freedom to restore a users C:\ drive without messing up the Firefox profile, or losing recent information, for example. We do the same for Thunderbird and several other applications.

The profile.ini file does live in its default location and points to the relavant folder path=F:\Users\<username>\profiles\<profilename> IsRelative=0

We backup a users PC with a comprehensive script which copies the profile.ini and Profiles folder. The group policy is also backed up, and in that policy we have set to use legacy profiles.

When we build a new PC for a user we restore those backups in the hope that the user will take up where they left off. For example, their browser history will be at the point is was when they left the PC.

The whole process is pretty automated. However, with FF91esr I cannot get it to use the folder we backed up. It ignores what's in the profiles.ini file and creates a new profile in the default location, set's it as default and of course sets IsRelative=1.

I tried several combinations of things to try to stop this, but in the end the ONLY way I could get it to use the restored profile was to go to about:profiles, create a new profile, point it to the folder where the restored profile is located, restart using the new browser, then via about:profiles, delete the bogus profile (of course having set the restored profile as default).

I'm not going to sit at 250 PCs doing that. It's crazy.

How can I get FF to use the restored profile folder and stop it endlessly creating new profile folders?

So far I've only tested with clean installs of FF91esr, so this is not an issue with different versions of profiles. But I am concerned over what's going to happen when I update Firefox on a PC...

I work on computers without admin rights, and i can't install add-ons,

how to make a true portable Firefox without using registry at all

I really don't understand that a free software allows such a blocking, even if chrome doesn't pose any problem with add-ons.

is there a way to lanuch firefox with a option to not use registry or to redirect registry in file or in a not locked custom registry like

hkey_local_machine/software/policies/Mozilla_portable/Firefox

or something like that ?

All of a sudden Firefox has ceased to react when I'm trying to download a file/save a page. When I click Cmd+S or File → Save page as…, nothing happens. When I try to open an upload dialogue, a solid gray window appears, and that's it. Uploading files through drag&drop interface works fine.

The problem seemingly appeared after migrating from a Mac Mini to a Macbook Air (both M1). I've already tried to restart the laptop and refresh Firefox — to no avail.

Is there anything else I could try to do?
